摘要： Route search devices, methods, and programs acquire basic congestion information, the basic congestion information being congestion information for specific links. The systems, methods, and programs set a destination and search for a first travel route from a departure point to the set destination using the acquired basic congestion information. Based on the first travel route, the systems, methods, and programs determine, whether center traffic information is necessary to be acquired. Only when it is determined that the center traffic information is necessary, the systems, methods, and programs acquire the center traffic information, the center traffic information being congestion information of a link other than the specific links, and search for a second travel route from the departure point to the set destination using the acquired additional congestion information.
摘要翻译：路由搜索设备，方法和程序获取基本拥塞信息，基本拥塞信息是特定链路的拥塞信息。系统，方法和程序使用获取的基本拥塞信息设置目的地并搜索从出发点到设定目的地的第一行驶路线。基于第一条旅行路线，系统，方法和程序确定中心交通信息是否需要获取。仅当确定需要中心交通信息时，系统，方法和程序获取中心交通信息，中心交通信息是除特定链路以外的链路的拥塞信息，并且从第使用所获取的附加拥塞信息到设定目的地的出发点。
